[hobbit] NCV Graph not showing up

[Maxeiner, Christian]

I tried that without success. Anyway this makes no sense because the
test name is "roomtemp", "Temperature" is just the value. 

My RRD-File seems to be ok. The problem seems to be in displaying the
graph. Is there a way to debug this? There are no error messages in the
logfiles.



 


	Try replacing "roomtemp" in hobbitserver.cfg with "Temperature".
I'm not sure if that makes a difference or not, though.  Also, make sure
the script doesn't generate any other text besides "Temperature:
<value>"...  I had a script that output some non-value text before the
actual text, which was causing NCV to try to parse that into a number
(and thus "NaN" - Not a Number). 
	
	
	
	

		Hi all,
		
		I have just tried to set up a custom NCV graph to
monitor the room 
		temperature.
		
		An external script generates a status page with the
following output
		(example):
		
		Temperature: 22.92
		
		I have added the following entries to my
hobbitserver.cfg:
		
		TEST2RRD="....,roomtemp=ncv" 
		
		NCV_roomtemp="Temperature:GAUGE"
		
		GRAPHS="...,roomtemp,ncv"
		
		My roomtemp.rrd File has been created and updates
regularly.
		Output of rrdtool dump:
		
		<rrd>
		        <version> 0001 </version> 
		        <step> 300 </step> <!-- Seconds -->
		        <lastupdate> 1145970097 </lastupdate> <!--
2006-04-25 15:01:37
		METDST -->
		
		        <ds>
		                <name> Temperature </name> 
		                <type> GAUGE </type>
		                <minimal_heartbeat> 600
</minimal_heartbeat>
		                <min> 0.0000000000e+00 </min>
		                <max> NaN </max> 
		
		                <!-- PDP Status -->
		                <last_ds> UNKN </last_ds>
		                <value> 2.1708600000e+03 </value>
		                <unknown_sec> 0 </unknown_sec> 
		        </ds>
		
		
		After that, I have added the following to my
hobbitgraph.cfg:
		
		[roomtemp]
		
		        TITLE Server Room Temperature
		
		        YAXIS degrees
		
		        DEF:temp=roomtemp.rrd:Temperature:AVERAGE 
		
		        LINE2:temp#FF0000:Room Temperature
		
		        COMMENT:\n
		
		        GPRINT:threads:LAST: \: %5.1lf (cur)
		
		        GPRINT:threads:MAX: \: %5.1lf (max)
		
		        GPRINT:threads:MIN: \: %5.1lf (min) 
		
		        GPRINT:threads:AVERAGE: \: %5.1lf (avg)\n
		
		There is no graph showing up on status page nor on the
trends page. On
		the status page there is only a link "hobbit graph
ncv:roomtemp" and on
		the trends page only a link "hobbit graph roomtemp".
		
		What am I doing wrong? Do I have to configure other
things than these?
		
		Thank you in advacne for answering.
		
		Chris
